T-Mobile 5G Gets Faster with Launch of Four-Carrier Aggregation

T-Mobile has launched a new feature of its 5G SA network that enables faster data speeds of up to 3.3 Gbps. The technology is called four-carrier aggregation (4CA) and it combines four different channels (carriers) of radio spectrum to act as one, enabling faster data rates than any one frequency band could offer. T-Mobile launched three-carrier aggregation (3CA) at the end of 2022, offering data speeds of up to 3 Gbps. T-Mobile's new 4CA mode consists of two channels near 2.5 GHz (both within the very wide band 41), one near 1900 MHz (band 2/25), and another near 600 Mhz (band 71). T-Mobile says 4CA is available "in parts of T-Mobile’s network now and will be available nationwide in the coming weeks." The only phone that can currently take advantage of T-Mobile 4CA is the Samsung Galaxy S23, "with more devices to follow."
